About “Sherane a.k.a Master Splinter's Daughter”

The story opens as a flash-forward. K.Dot has known Sherane for a number of months by this point. He met her at a party where they flirted and exchanged numbers. They kept in contact with each other over the summer and got to know each other pretty well. He also talks about her family’s history of gang-banging that made him wary but didn’t stop him from hooking up with her.
At the end of this song K.Dot is driving to Sherane’s house in his Mother’s van, he has sex on the brain. But when he turns up Sherane is outside waiting with two dudes in black hoodies (possibly her two younger brothers, or her cousins, one of which could be Demetrius).

This isn’t the first time Kendrick has evoked the humanoid rat father-figure of the Teenage Mutant Turtles, Master Splinter. See: The Heart Pt. 2

The “Master Splinter” part of the title likely signifies Sherane’s “hoodrat” status.
